Advantages
Braid coverage up to 85%-95%, effectively blocks electromagnetic interference (EMI) and radio frequency interference (RFI) with excellent attenuation.
Cu-ETP C11000 pure copper ensures extremely low grounding impedance for the shield, improving signal integrity.
Braided structure easily bends and wraps, suitable for tight bending radii and dynamic flexing cables without damaging inner insulation.
Tin-plated copper shielding wires provide better corrosion resistance in humid, salt spray or sulfur-containing environments, extending service life.
Various wire diameters, cross sections and braid densities available. Precise matching based on customer-provided conductor diameter, no MOQ restriction.
Operating Conditions
Bare copper -40°C to +150°C; tin-plated copper -40°C to +150°C (short-term up to +180°C).
Bare copper for dry indoor use; tin-plated for humid, salt spray, mild acid/alkali and industrial polluted areas.
The braid shall evenly cover the inner conductor. Ensure reliable contact with grounding rings or shield clamps when grounding both ends. Bending radius ≥5 times outer diameter of shielding wire recommended.
For shielding in 100kHz~1GHz frequency range; grounding resistance should be as low as possible (<10mΩ).
Maintenance
Every 6 months check for broken strands, oxidation/discoloration (bare copper) or tin peeling (tin-plated).
Blow off dust with dry, oil-free compressed air; for oil contamination, wipe gently with an alcohol swab and dry thoroughly. Do not use acidic or alkaline cleaners.
Check tightness of grounding connections at both ends; measure shield-to-ground resistance.
Prevent sharp edge scraping or over-stretching during installation and use to avoid reducing shielding coverage.
Service Life
Under normal indoor conditions (-40°C to +120°C, no corrosive gases, static installation), the designed service life of copper shielding wires is 15-20 years. Tin-plated copper shielding wires can achieve 12-15 years in humid or mildly corrosive environments.
Thanks to pure copper material and single-layer braid construction, no replacement is needed within the normal service life of the cable.
For frequent flexing or vibration applications, it is recommended to check continuity and coverage every 2-3 years.
